feat(slides): fill xml-schema-quick-ref gaps that forced XSD fallback

[R0bynZhu]

From EVAL-07-22-02-53 (42 convos), agents fell back to the full XSD for:

• shape type enum + presetHandlers (rounded corners)
• polyline (bounding-box positioning, required border, connector type)
• table merged cells (colspan / rowspan)

Add compact coverage for each, sized to real usage (shape/polyline type lists trimmed to what actually appears in generations). Chart gaps deferred.

Summary by CodeRabbit

• Documentation
  • Added guidance on XML shape type values and optional attributes (including handler and custom-only path behavior).
  • Expanded <polyline> documentation with rules for external-rectangle positioning, required <border> settings, and connector type defaults/choices.
  • Clarified table cell merging: use <td> colspan/rowspan, and merged/covered cells no longer define additional <td>.
